Re: [Zope] RE: CST and disappearing variables (still)

      It'd be useful to have a log of session activity for session start and end
(use the sessioning onStart and onEnd mechanisms to do this) as well as a
log method to use before you access a session data object.. you could make a
couple external methods that log session events to the STUPID_LOG.

An onstart script follows:

def sessionOnStart(self, sdo):
    sdm = self.SDM
    isnew = sdm.isTokenNew()
    sd_sid = sdo.id
    sd_pyid = id(sdo)
    s = "%s pyid %s sid %s" % (isnew and 'new token ' or '',
                               sd_pyid, sd_sid)
    from zLOG import LOG, INFO
    LOG('Session onStart', INFO, s)

An onend script follows:

def sessionOnEnd(self, sdo):
    from zLOG import LOG
    LOG('Session info', zLOG.INFO, 'Session sid %s ending' % sdo.id)

Additionally, before you access any sessioning stuff in your code it would
be useful to call a logging method like this:

def logSessionInfo(self, sdm, from=''):
    sdo = sdm.getSessionData()
    isnew = sdm.isTokenNew()
    sd_sid = sdo.id
    sd_pyid = id(sdo)
    sd_len = len(sdo)
    s = "%s pyid %s sid %s len%s" % (isnew and 'new token ' or '',
                                     sd_pyid, sd_sid, sd_len)
    from zLOG import LOG, INFO
    LOG('Session info (%s)' % from, INFO, s)

Use this method like so from dtml *before* every call to your sessioning
machinery.

 <dtml-call "logSessionInfo(SDM, 'test method')">

When you run into a situation where you suspect a sessioning problem, send
me the relevant time period from the logfile (set via STUPID_LOG_FILE).

HTH,

No, it seems normal. :-(  Darn.
You're not working with multiple frames or windows, are you?
Nope.
Any suggestions on how I could set something up to gather debugging
information?  Like placing something (though I'm not sure what) in various
places in my code to log whatever may be going on with the request and
session?
I'm just grabbing at straws now.  I really have no idea where to go with
this, but I'm nervous about starting a large upcoming project that would
use
CST quite a bit when I'm having random problems.
